I use big and well matured libraries for the critical parts of my code. These can be logging, option/file parsing, or linear algebra. When I add these libraries, I use most parts of them at the end of the day. However for other one-off things like internal state handling or stuff which I can prop up using the standard library, I refuse to use external libraries. I kindly disagree on the part of they're not getting a better product. On the contrary. They require to manage less dependencies, most critical parts are well cooked/tested, and other parts are built using the standard library which is built to build these things. When rolling things forward, I need to juggle less dependencies, too. So things can move forward easier. It's not like I'm banging the keyboard and shouting done when it prints something meaningful to screen.
